Rack stand



FIG. 1 is an isometric view of a rack stand, showing my new design, from the front, top, and left side;

FIG. 2 is a top plan view thereof;

FIG. 3 is a bottom plan view thereof;

FIG. 4 is a front elevational view thereof;

FIG. 5 is a back elevational view thereof;

FIG. 6 is a side elevational view, slightly enlarged, thereof from the left side;

FIG. 7 is a side elevational view, slightly enlarged, thereof from the right side; and,

FIG. 8 is an isometric view showing my new design from the front, top and left side, wherein the phantom representation of the informational units is made for the purpose of illustrating the environment in which the rack stand is used.

The broken line disclosure of environment forms no part of the claimed design. 

I claim the ornamental design for a rack stand, as shown and described.
